Half of the country's uninsured kids live in just six states. Arizona is the fifth on that list, with an estimated 208,419 kids without coverage -- about 3.8 percent of all the country's uninsured kids. That's only slightly higher than the sixth state -- New York. But Arizona has only a third of New York's population, meaning that New York's kids are much better covered.

Part of the problem is that tens of thousands of Arizona kids lost coverage starting in early 2010, when Governor Jan Brewer signed a bill to get rid of public coverage for children in order to help balance the budget. An estimated 47,000 children lost coverage.
